Software Tester | Manual Tester | QA Tester

As a Manual Software Tester, I specialize in identifying and reporting software issues that impact user experience, functionality, and overall product quality. Through my work with platforms like TesterWork, Test.io, UTest, Ubertesters, and Korro AI, I have encountered various software challenges, including: - Buggy User Interfaces – UI elements that fail to display correctly, causing usability issues. - Functionality Failures – Features that do not work as intended, such as broken login systems, crashes, and API failures. - Performance Bottlenecks – Apps that freeze, slow down, or fail under certain conditions. - Compatibility Issues – Differences in behavior across devices, browsers, and operating systems. - Security Vulnerabilities – Exposed user data, weak authentication, and potential exploits. What I Offer: - Thorough Exploratory Testing – I manually test software across different environments to uncover hidden defects. - Detailed Bug Reporting – I document issues with clear steps, screenshots, and severity levels to help developers fix them efficiently. - User-Centric Approach – I focus on how real users interact with software, ensuring an intuitive and seamless experience. - Regression Testing – I verify that new updates do not break existing functionality. - Collaboration & Feedback – I communicate findings effectively with developers, product teams, and stakeholders. With experience across mobile, web, and AI-powered applications, I help businesses improve software quality by catching critical bugs before they reach end users.
